1.5.0 also comes with a new loss condition: Stranded. As of this update, the train starts with just three beacons. If you use them all and run out of both passengers and fuel, it's game over. Don't worry, if you prefer the old way of doing things, a new modifier is available that provides unlimited beacons.

For users with less powerful system configurations, we've added a low-quality lighting mode, which can be set in the Graphics options. This should provide a healthy framerate boost, at the expense of visual fidelity.

We've also tweaked a few balance dials behind the scenes. The biggest change is that engine upgrades now boost the train's speed. However, damaged carriages will slow you down. To help you keep track of these bonuses and penalties, a new card with all the information you need has been added to the route plotting notepad in the front cabin.

Next up, Fearless are now much more of a threat. If you happen to experience a fear attack in the same sector as a Fearless unit, your train's defences against that attack will be halved. All the more reason to give the Fearless a wide berth...

Finally, hungry passengers will last longer before perishing and upgrades at higher tiers now require more time to complete.

For the nitty-gritty of 1.5.0, check out the full changelog:

Added: Five new fears: Witches, Buried, Spirits, Wasps and Snakes.

Added: "Stranded" loss condition. As of 1.5.0, the train starts with three signal beacons instead of an unlimited supply. Once these are expended and the train has no fuel and no passengers, the game will end in a loss. Modifiers are available for custom engineers to alter the beacon limit. This change does not affect games currently in progress.

Added: A card on the route plotting notepad that show the bonuses and penalties currently affecting the train's speed.

Added: Lighting Quality graphics option. This changes the rendering pipeline from deferred shading to deferred lighting, which results in a loss of lighting fidelity, but can substantially improve performance on low-end systems. Note that on the "Low" setting, directional occlusion is replaced with ambient occlusion.

Added: A detailed explanatory note regarding fear attacks now appears after the first such event. Players will find it positioned near the bed.

Added: Ambient noises from the first carriage can now be heard in the Engineer's cabin.

Added: Epilogue text is now exported when the game ends. On Windows, epilogues are stored in "My Documents\Fear Equation\Epilogues". On OS X, epilogues can be found in "Users/<USERNAME>/Documents/Fear Equation/Epilogues", where "<USERNAME>" is your OS X user name.

Balance: Increased the time it takes to complete upgrades at higher tiers.
